Scientists link global warming to lower sulfur pollution from ships. Fewer ship aerosols mean less sunlight reflection, allowing heat to stay.

The virus winter season has struck—and COVID-19 is still part of everyday life. However, unlike during the pandemic, we now know more about how it spreads through the air we breathe. Research from ...

Last year, 2024, was the warmest year on record for the planet, easily breaking the previous record set just a year earlier.

On January 9, approximately a full day after the Eaton fire devastated the foothill area of Altadena, north of the Caltech ...

Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around ...

Air cleaners and ventilation systems, meant to reduce airborne infections in hospitals, may have unexpected effects, ...

A group of South Korean researchers has developed an intelligent fire detection technology that drastically reduces false ...

Aerosol science, the study of airborne particles from the nanometre to the millimetre scale, has been increasingly in the public consciousness in recent years, particularly due to the role played by ...

Aerosols directly influence the earth’s radiation balance by reflecting some of the sunlight back into space. But aerosol particles with dark surfaces (like soot) can also absorb visible light and ...

Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around ...

A group of South Korean researchers has developed an intelligent fire detection technology that drastically reduces the false alarm incidents, which go off in the absence of a real fire, and is on the ...
